When the worm is run, it creates a copy of itself with a random name in the Windows directory and adds a registry value containing the name of the file to HKLM\Software\Microsoft\Windows\CurrentVersion\RunOnce. It then searches the Outlook address book and examines files with the extensions .CGI, .HTM, .SHTM, .PHP and .PL to find email addresses to which it can spread.
